 | | Audio was generated by a built-in sound and music synthesizer in the form of the Ensoniq Digital Oscillator Chip (DOC), which had its own dedicated RAM and 32 separate channels of sound, which were paired to produce 15 voices, in stereo audio. |
 | | Apple Records considered the inclusion of the Ensoniq chip in the II as a violation of that agreement. |
 | | However, it provided only mono sound through this jack, and a third party adapter card was required to produce true two-channel stereo, despite the fact the Ensoniq and virtually all native software produced stereo audio (stereo audio was essentially built-in to the machine, but had to be demultiplexed by third party cards). |
